when burning, smoke and give forth an odor proved Apparatus for Treating f: armaarus on TRE ING BR'I'IQUETTES.

Application filed October 5 To all whom a my concern: Be it known that I, CARSTEN IIJOHNSEN, a citizen 'of the United stateg and 'a-resident of the city of'NewYork'; borough of Brooklym-in the county of Kings and State of N ew"York, have invented a new and Ims A Briquettes, of which the following is a full, clear, and exact description. 7 I

This invention relates to improvements in conveying apparatus primarily utilized in the treatment of-briquettes j f In the manufacture of coal-"briquettes, a binder is usually employed, the nature of which is .such that the briquettes now used,

of sulphurdioxide. Furthermore, briquettes as now made are, not waterproof due tothe condition of the binder after the briquettes have been formed.=- I

An object of the present' invention is-to overcome th'eabove difiiculties by treating the briquettes in 'su'ch manner that-the binder will be dried andfcarbonized or charred to make the briquettes waterproof and to prevent the binder from breaking down into its constituents with the result that the briquettes will be smokeless and ordorless when burning; v

Another object is to provide an apparatus in which briquettes to be treated are transmitted through a heating furnace by an endless conveyor and subjected to the heat in 'said' furnace sufficiently long to effect the complete dryingi andcarbonization of the binder. Y

The above and other objectswill appear more clearly from the following detail description when taken in connection with the accompanying drawings .which illustrate a preferred embodiment of the inventive idea.

In the drawings Figure 1 is a fragmentary section through the apparatus;

Figure 2 is a section substantially on the line 2-2 of Figure 1;

Figure 3 is a fragmentary transverse section through the apparatus; and

Figures 4 and 5 are fragmentary yiews in top plan and side elevation, respectively, of the conveyor employed in connection with the invention.

Referring more particularly to the accompanying drawings, the numeral 6 indicates a furnace which may be of substantially oval formation in top plan, as shown in longitudinal pose which will presently appear.

of the furnace 6 is provided with forming an outlet for. the heat and Directly above the grate Mounted'in the bearings 12 are the lower 'ends' of two shafts Band 14, the upper end of the shaft 13 extending through the top ofthe furnace and mounted in a stationary bearing 15, while the upper end of the shaft'l f is supported in a bearing 16 movable longitudinally in a supporting member 17 for a purpose which will laterappear. 12, which supports the lower iaft 14',"is shown in more detail and includes relatively movable permit of a slight rocking' movement of the lower end of the shaft 14 when the upper end thereof is moving longitudinally in the supporting member 17. The shafts 13 and 11 are inclined or arranged diagonally with respect to longitudinal and transverse vertical planes exend ofthe s tending through the furnace, as shown in Trections so that the upper and lower ends of said shafts will be disposed on opposite sides of a medial longitudinal vertical plane extending through the furnace. Also with respect to a medial transverse vertical plane extending through the furnace the shafts are so inclined that the lower ends thereof will be spaced a greater distance apart than the as clearly shown in Figure 1. Carried by each of said shafts in super posed relation thereon are a plurality of propelling elements arranged in planes at right of rotation of the shaft upon which they are mounted and thus being pitched with respect to the horizontal in accordance with the inclination of the respective shafts. By thus arranging the propelling elements, it will be seen in Figures 1 and 3, that the elements carried by one shaft are inclined or pitched in opposite directions with respect to the elei said furnace and also extending in opposite" directions relative to each other, propelling --on one shaft being in staggered relation and inclined in opposite directions with respect to those on the other shaft, an endless conveyor extending around said elements, and carriers supported on said conveyor.

3. In a conveyor apparatus utilized for the passage of briquettes through a heating furnace, rotatable shafts in said furnace each I t of which is inclined upwardly in opposite directions with respect to a plane extending 2 through said furnace, propelling elements carried by each shaft and arranged in staggered relation with respect to the elements .on the other shaft, an endless conveyor ex- "tending around said elements, and carriers flsiupported on said conveyor. n Y i 4. In a conveyor apparatus utilized for the passage of briquettes through a heating furnace, rotatable shafts in said furnace, each of which is arranged diagonally with elements carried by each shaft, the elements 4 respect to vertical intersecting planes extending through said furnace and in opposite directions relative to each other, propelling elements carried by each shaft, an endless conveyor extending around said elements, and carriers supported on said conveyor.

5. In a conveyor apparatus utilized for the passage of briquettes through a heating furnace, rotatable shafts in said furnace each of which is arranged diagonally with respect to vertical intersecting planes extending through said furnace and in opposite directions relative to each other, propelling elements carried by each shaft, an endless conveyor extending around said elements, and carriers supported on said conveyor and alternately arranged indifferent planes with respect to the plane of said conveyor and the ends of each carrier in one plane overlapping the adjacent ends of the next adjacent carriers in the other plane.

6. In a conveyor apparatus utilized for the passage of briquettes through a heating furnace, shafts rotatable in said furnace'and arranged diagonally with respect to vertical intersecting planes, a bearing for one of said shafts having a sliding movement relative to the othershaft, means engageable with said bearing compensating for heat expansion within said furnace, propelling elements carried by said shafts, a conveyor extending around said elements, and carriers mounted on said conveyor.
